Nicht hackbare Rechner und nicht brechbare Kryptographie
by Wolfgang A. Halang Robert FitzViren, Würmer, Trojanische Pferde, das Arsenal der Hackerangriffe auf IT-Infrastrukturen scheint unerschöpflich. Nachdem Computerwurm Stuxnet 2010 das Steuerungssystem eines iranischen Atomkraftwerks befallen hatte und Computer durch die Malware Flame ferngesteuert und ausspioniert wurden, sorgte 2015 ein Virus namens Duqu 2.0 für Schlagzeilen, weil er die IT von Unternehmen in Europa, Asien und den USA infiziert hatte. Was aber wenn Computer grundsätzlich gegen solche Hackerangriffe immun wären? Wissenschaftlich fundiert und zugleich verständlich geschrieben, zeigen die beiden IT-Experten in ihrem Buch, wie Computer mithilfe von bekannten technischen Verfahren so konstruiert werden können, dass Hackerangriffe grundsätzlich an ihnen abprallen. Zum einen setzen die Autoren für die IT-Sicherheit auf eine Rechnerarchitektur, die in mindestens zwei Segmente unterteilt ist: in einen schreibgeschützten und für Programme nicht beeinflussbaren Bereich sowie einen nicht-schreibgeschützten Bereich für Daten gibt, die sich oft ändern. Kombiniert unter anderem mit effektiven Verschlüsselungs- und Verschleierungsverfahren, einer sichereren Authentifizierung der Nutzer etwa durch biometrische Merkmale sowie sicheren virtuellen Adressen und Seitenverzeichnisstartadressen werden Computer unangreifbar für Software, die unerlaubt in den Rechner eindringt und Daten abschöpft.Die Autoren gehen in ihrer technisch-wissenschaftlich exakten Darstellung auf folgende Fragen ein:- Wie sicher sind Rechner und Netze heute?- Wie funktionieren Angriffe mit Stuxnet, Flame und Duqu und wie die Methoden zu ihrer Abwehr?- Welchen Schutz bieten Harvard- und Von-Neumann-Architekturen (VNA)?- Wie sehen neuartige Schutzmaßnahmen aus und wie können mobile Geräte geschützt werden?- Wie funktioniert sichere Datenverschlüsselung und -verschleierung?Das Buch richtet sich an IT-Experten und IT-Sicherheitsverantwortliche in Unternehmen und Organisationen und an alle, die sich für Fragen der Daten- und Netzsicherheit interessieren. Für das Verständnis sind nur elementare Vorkenntnisse erforderlich.

New Trends in Aggregation Theory (Advances in Intelligent Systems and Computing #981)
by Radomír Halaš Marek Gagolewski Radko MesiarThis book collects the contributions presented at AGOP 2019, the 10th International Summer School on Aggregation Operators, which took place in Olomouc (Czech Republic) in July 2019. It includes contributions on topics ranging from the theory and foundations of aggregation functions to their various applications. Aggregation functions have numerous applications, including, but not limited to, data fusion, statistics, image processing, and decision-making. They are usually defined as those functions that are monotone with respect to each input and that satisfy various natural boundary conditions. In particular settings, these conditions might be relaxed or otherwise customized according to the user’s needs. Noteworthy classes of aggregation functions include means, t-norms and t-conorms, uninorms and nullnorms, copulas and fuzzy integrals (e.g., the Choquet and Sugeno integrals). This book provides a valuable overview of recent research trends in this area.

Sociality and Normativity for Robots
by Raul Hakli Johanna SeibtThis volume offers eleven philosophical investigations into our future relations with social robots--robots that are specially designed to engage and connect with human beings. The contributors present cutting edge research that examines whether, and on which terms, robots can become members of human societies. Can our relations to robots be said to be "social"? Can robots enter into normative relationships with human beings? How will human social relations change when we interact with robots at work and at home? The authors of this volume explore these questions from the perspective of philosophy, cognitive science, psychology, and robotics. The first three chapters offer a taxonomy for the classification of simulated social interactions, investigate whether human social interactions with robots can be genuine, and discuss the significance of social relations for the formation of human individuality. Subsequent chapters clarify whether robots could be said to actually follow social norms, whether they could live up to the social meaning of care in caregiving professions, and how we will need to program robots so that they can negotiate the conventions of human social space and collaborate with humans. Can we perform joint actions with robots, where both sides need to honour commitments, and how will such new commitments and practices change our regional cultures? The authors connect research in social robotics and empirical studies in Human-Robot Interaction to recent debates in social ontology, social cognition, as well as ethics and philosophy of technology. The book is a response to the challenge that social robotics presents for our traditional conceptions of social interaction, which presuppose such essential capacities as consciousness, intentionality, agency, and normative understanding. The authors develop insightful answers along new interdisciplinary pathways in "robophilosophy," a new research area that will help us to shape the "robot revolution," the distinctive technological change of the beginning 21st century.
Cyber-Physical Security: Protecting Critical Infrastructure at the State and Local Level (Protecting Critical Infrastructure #3)
by Simon Hakim Robert M. ClarkThis book focuses on the vulnerabilities of state and local services to cyber-threats and suggests possible protective action that might be taken against such threats. Cyber-threats to U. S. critical infrastructure are of growing concern to policymakers, managers and consumers. Information and communications technology (ICT) is ubiquitous and many ICT devices and other components are interdependent; therefore, disruption of one component may have a negative, cascading effect on others. Cyber-attacks might include denial of service, theft or manipulation of data. Damage to critical infrastructure through a cyber-based attack could have a significant impact on the national security, the economy, and the livelihood and safety of many individual citizens. Traditionally cyber security has generally been viewed as being focused on higher level threats such as those against the internet or the Federal government. Little attention has been paid to cyber-security at the state and local level. However, these governmental units play a critical role in providing services to local residents and consequently are highly vulnerable to cyber-threats. The failure of these services, such as waste water collection and water supply, transportation, public safety, utility services, and communication services, would pose a great threat to the public. Featuring contributions from leading experts in the field, this volume is intended for state and local government officials and managers, state and Federal officials, academics, and public policy specialists.

by Jawad Haj-Yahya Avi Mendelson Yosi Ben Asher Anupam ChattopadhyayThis book explores energy efficiency techniques for high-performance computing (HPC) systems using power-management methods. Adopting a step-by-step approach, it describes power-management flows, algorithms and mechanism that are employed in modern processors such as Intel Sandy Bridge, Haswell, Skylake and other architectures (e.g. ARM). Further, it includes practical examples and recent studies demonstrating how modem processors dynamically manage wide power ranges, from a few milliwatts in the lowest idle power state, to tens of watts in turbo state. Moreover, the book explains how thermal and power deliveries are managed in the context this huge power range. The book also discusses the different metrics for energy efficiency, presents several methods and applications of the power and energy estimation, and shows how by using innovative power estimation methods and new algorithms modern processors are able to optimize metrics such as power, energy, and performance. Different power estimation tools are presented, including tools that break down the power consumption of modern processors at sub-processor core/thread granularity. The book also investigates software, firmware and hardware coordination methods of reducing power consumption, for example a compiler-assisted power management method to overcome power excursions. Lastly, it examines firmware algorithms for dynamic cache resizing and dynamic voltage and frequency scaling (DVFS) for memory sub-systems.
